(06-27) 16:55 PDT SAN FRANCISCO -- A warming trend is coming just in time for the weekend in the Bay Area, with temperatures expected to peak Sunday through Tuesday and even approach the triple digits in some inland areas, forecasters said.

San Francisco, which is hosting the Pride festivities this weekend, will be typically mild, with temperatures hovering in the lower 70s Sunday and Monday.

But those who venture east will feel the heat. Concord and Livermore should reach temperatures in the 90s by Sunday and climb higher on Monday, said Bob Benjamin, a forecaster with the National Weather Service.

In Brentwood, highs of 102 on Monday and 100 on Tuesday are forecast.

The North Bay will see balmy weather as well with temperatures in the mid to high 80s expected on Sunday, Monday and Tuesday in Santa Rosa.

The weather service, however, said no heat advisories, warnings or watches are in place at this time. While fire danger is high, winds are expected to be relatively calm.

Temperatures will gradually return to normal in the Bay Area next week, with San Francisco back to highs in the 60s by Thursday, Benjamin said.
